Each account can vote for 30 witnesses. Isn't that too much? Wouldn't it be fairer to reduce it to 10? Someone with 90 million HP of voting power can choose the witnesses they want. If we want decentralization to decrease, a change must be made here. But since being able to vote for 30 is in favor of the first 20 witnesses, I don't think they will want to change this.
LF witness can develop new strategies to enter the top 20. You earn tokens when you vote for witnesses on other blockchains. LF witness can also distribute LEO tokens.
